PU LVERIZER.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed February 16, 1909. Serial N 0. 478,211.

Be it known that I, IVIILTON J. WILLIAMs, a citizen of the United States, residing at Chicago,"Illinois, have invented a certain new and useful Improvement in Pulverizers, of which the following is, a'full, clear, and

skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, forming part of this specification, in which Figure l is a vertical sectional view, through a pulverizer constructed accordin fragmentary sectional view through the same.

This invention relates to a new and useful improvement in pulverizers of that type ebmmercially known as the \Villiams mills characterized by the pivoted revolviug hammers which act upon the material as it enters the machine at the hopper or feed end thereof, crushing said material as it breaker plate, as it is sometimes called, 'the material being further disintegrated or the material is carried over the cage or grinding surface. The crushed material falls through the openings in the cage or grinding surface into a suitable receptacle located beneath the machine. The hammers or beaters which revolve about the ance to wear is its essential quality, will, in tune, wear away at their striking ends, and the farther these striking ends are removed face, the less becomes the capacity of the It is the purpose of my present invention to provide means whereby these revolving hammers or beaters may be adjusted outif occasion requires, as when a new cage is introduced .to, replace a worm one), said means being operable from the outside and effecting the simultaneous and uniform adjustment of all of the hammers or heaters. In the drawings, 1 indicates the casing, 2 the breaker plate, 3 the grinding surface or cage, aud t the cover of the machine, which may or may not be hung, as desired. 5 is a shaft mounted in hearings in the shaft carrying a pulley 6 and the other end,

from the' nature and a balance wheel (not shown), if desired.

\Vithin the casing of the machine, shaft 5 is enlarged and made hollow to receive a longitudinally adjustable cone 7, the apical end of which is provided with a guiding flange 7. Threaded rods 8 project from each end of the cone through the shaft 5, they being provided with nuts 9 on their ends, by which the cone may be adjusted longitudinally within its chamber.

Arranged about the shaft 5 are lugs 10 in which are mounted rods 11. On these rods are levers 12 whose inner ends pass through openings in the enlarged portion of shaft 5 and bear against the cone 7. The outer ends of levers 12 carry pivoted hammers 13 which act upon the material to be reduced in the machine.

In operation, if the hammers 13 wear at their striking ends the cone 7 is adjusted so that the inner ends of all of the levers ride down inclined surface of the cone, which causes the hammers to move outwardly, such 1 outward movement taking up the wear on the hammer ends. The outer ends of levers- 12 are the most heavily weighted, and consequently centrifugal force will act upon such outer ends of said levers causing their inner ends at all times, in operation, to hug the surface of they cone. When the proper adjustment has been effected, the cone is locked against longitudinal displacement by the nuts 9.

I am aware that minor changes in the construction, arrangement and combination of the several parts of my. device can be made and substituted for those herein shown and described without in the least departing principle of ,my invention. I

Having thus described my invention, what I claim is:

1. In a pulverizer, the combination with a casing, of a rotating element therein, hammer supports carried by said element, longitudinal rows of pivoted revolving hammers mounted on said hammer supports and means adjustable in a direction across the path of movement of said hammers for engaging the hammer supports and taking up wear at the ends of'the hammers.

2. In a pulverizer, the combination with a casing,'of a rotatingelement therein, longitudinal rows of pivoted revolving hammers arrangedon said rotating element, each of said hammers having supports of various lengths depending upon the position of the hammer in the row, and means cooperating with said hammer supports for taking up wear at the ends of the hammers.

3. In a pulverizer, the combination with a casing, of'a shaft mounted therein, a member carried by said shaft within the casing,

the inner ends of said hammer supports of various lengths carried by said member, hammers pivotally connected to said hammer supports, and means adjustable lengthwise the shaft for coiiperating with said hammer supports to take up wear at the ends of the hammer supports.

t. In a pulverizer, the combination with a casing,- of pivotally revolving hammers arranged therein, a cylindrical member for carrying said hammers, and a threaded rod and cone within said cylindrical member for adjusting said hammers inwardly and out- \rardly, said rod extending through the end of the cylindrical member and provided at its extremity with a nut for locking the parts I r cylindrical member, adjustable means within in theiradjusted positions.

In a pnl'verizer, the combmation with a casing, a cylindrical member mounted therein, lovers of various lengths mounted upon said cylindrical member, hammers pivotally mounted on the outer ends of saidlevers,

and an adjustable cone arranged within the cylindrical member and cooperating With lengths.

levers of varyingi esavee member joui'naled for rotation therein, a 3

series of revolving hammers pivotally ar ranged on the cylindrical member, and

means arranged within the cylindrical meniber for adjusting the hammers outwardly to take up the wear on the ends thereof, which means is adjustable from the exterior of the cylindrical member. 3

8. In a pulverizer, a casing, a cylindrical member journaled for rotation therein, a series of levers pivotally arranged on the the cylindrical member for engaging the inner ends of all of the levers, and revolving hammers pivotally connected to the outer ends of the levers.

In testimony whereof I hereunto affix my signature in the presence of two witnesses,

i this'Sth day of February, 1909.
